Abstract: ABSTRACT OF THE DISCLOSURE        A method and apparatus are provided for controlling the amount of dry particulate matter and liquid added to a ro-tary pelletizer.  A transducer senses a characteristic of the mixed material in the pelletizer.  The transducer signal is then conditioned to provide a signal level corresponding to a desired characteristic level and which varies about that level corresponding for example to the variations of pellet size about a desired size.  That signal is added to a second signal representing either the actual liquid flow actual dry particu-late flow into the pelletizer and modulates that respective flow to maintain the input of either the dry particulate or the liquid material into the pelletizer as necessary.  Addition-ally, a set point signal can be provided as a constant signal representing desired dry particulate in flow or liquid in flow.          The dry or the liquid signal also can be derived from the res-pective actual liquid or dry signal by taking a proper propor-tion of the other signal.

Abstract: Abstract of the Disclosure In fabricating a III-V compound, for example, GaAs, having a layered structure a first layer is grown on a planar substrate by a vapour deposition process adapted to produce differential growth while a subsequent layer is grown by a deposition process which restores planarity.  In this way a uniformly thick combination layer is produced with a non-planar junction between its composite layers.  Particularly in the fabrication of channelled substrate double heterostructure lasers, a channelled blocking layer is grown by organo-metallic pyrolysis (OMP) and a subsequent confining layer is grown using liquid phase epitaxy (LPE).  The OMP process produces a channel with flanking shoulder portions which permit LPE growth of a very thin confining layer immediately above the shoulder portions thereby improving linearity of the device.                             -i-

Abstract: Abstract of the Disclosure A vibration absorber for resonance vibrations of rotating bodies, in particular rail wheels, comprises several oscillatory plates which form or carry the mass, are separated from one another by intermediate layers of damping material and which are connected at at least one point rigidly with the rotating body and are coupled to the rotating body in the remaining area by way of an intermediate layer of damping material.  The plates (1,2,11,12, 15-18) and the intermediate layers (6,7,8,9,22-25) are tuned to one another with respect to their geometric dimensions, and the shore hardness of the damping material of the intermediate layers (6-9,22-25) is that all plates (1,2,11,12,15-18) oscillate with the natural frequency of the rotating body (4,10) to be damped.  The amplitudes and phases of the vibrations of the individual plates (1,2,11,12,15-18) are in such a relationship to one another that the damping material is as strongly distorted as possible.

Abstract: ABSTRACT OF THE DISCLOSURE      A disposable tray for heating comestibles to obtain a deep fried appearance and texture of the resultant products by maximizing convective heating of the comestibles and minimizing conductive heating thereof.  The top surface of the tray has a waffle design with an array of raised ridges thereon for supporting the comestible products on the ridge crests while minimizing conductive heat transfer thereto.  A plurality of round aperatures are pro-vided in the tray surface between the ridges to allow heated air to flow therethrough to convec-tively heat the products.  Raised frustoconical shaped fins are provided around the apertures, with the fins rising to a portion of the height of the ridges.  The fins function to increase the convec-tive flow of hot air through the apertures while not providing substantial contact with the comestibles. The raised fins also form troughs around the aper-tures to collect oil released by the products during heating thereof.

Abstract: TRAFFIC BARRICADE            Abstract of the Disclosure A traffic barricade is constructed from a foldable material such as double-faced corrugated plastic or cardboard impregnated with a waterproofing material.  First and second flat sheets of such material are provided, each having a pair of scorelines, the first of which defines a border of a vertical area and the second of which forms a border of a horizontal area when the barricade is erected.  The flat sheets each have a sloping surface between the scorelines when the barricade is erected.  The vertical areas of the two flat sheets are permanently secured to each other.  Also, one of the horizontal areas includes foldable edges that can be erected to an upright position to form a tray for receiving ballast materials to anchor the barricade in place.  One of the horizontal areas extends between the sloping surfaces of the sheets to maintain the second scorelines in spaced apart relation.        In one embodiment, a warning light is incorporated within the traffic barricade by forming holes in the vertical areas and attaching plastic lenses over each of the holes.  A light source is disposed between the lenses.  A flap formed within one of said flat sheets is folded to form a tray for supporting a battery to power the light source.

Abstract: ABSTRACT           A method for measuring the thickness of an ice sheet is dis-closed.  The resistance of an electric circuit embedded in an ice sheet floating at the surface of a body of water is measured.  A relationship between the measured electric resistance and the ice sheet thickness is possible because sea ice has a much larger resistance than sea water and, therefore, acts as an insulator.  Thus, the resistance of the circuit is altered by the vertical location of the water's surface on the circuit.
